87 – Francium – Fr
Francium is the least-stable naturally occurring element with a half-life of 22 minutes, and was the last element discovered in nature (in 1939 in…FRANCE!)
Francium should be the most reactive of the alkali metals, but it is so radioactive, that we’ve never put together a lump of it big enough to test.
